ABB ACS580 Modbus register map
General-purpose AC drive from ABB with a standard control program. The embedded fieldbus interface speaks Modbus RTU over EIA-485 and gives access to control and status words, two references, two actual values, and every drive parameter through a mapped register range.
- Protocol
- Modbus RTU (embedded fieldbus, EIA-485)
- Defaults
- Node address 1, 19.2 kbit/s, 8 data bits with even parity and 1 stop bit, ABB Drives control profile, addressing mode 0, word order low word first (p. 572-573). Settings in group 58 take effect after a reboot or after parameter 58.06 is set to Refresh settings.
- Addresses in the manual
- Modicon style numbers (for example 40001 is holding register 0)
- 32 and 64-bit values
- Low word first (CD AB)
- Registers listed
- 66
- Checked against
- 3AXD50000016097 Rev J, effective 2025-10-01
Address base. The manual prints holding registers with six digits from 400001 to 465536, where 400001 is the first register, so the wire address is the printed number minus 400001 (p. 576, p. 591). Parameters are mapped into the 400101 to 465536 range by parameter 58.33: in mode 0 a 16-bit parameter sits at 400000 + 100 x group + index and a 32-bit parameter at 420000 + 200 x group + 2 x index (p. 442). Coil and discrete input references are not listed here because the manual's wording on their wire address is ambiguous. For example 400001 in the manual (Control word (default Data I/O 1)) is address 0 on the wire.
Word order. Applies to the 32-bit parameter registers. Parameter 58.34 selects the order: low word first is the default, high word first is the alternative; bytes inside each register are high byte first (p. 442).
Modbus Poll and the Modbus protocol itself count from 0. The "Wire address" column is the number to type into Modbus Poll.

Open in Modbus Poll
- Download the Modbus Poll blocks file.
- Open Modbus Poll, connect to the device and set its unit ID. In Modbus Poll set Word order to CD AB.
- In the blocks panel on the right, click Import CSV and pick the file. CSV import is a Pro feature. Without Pro, Modbus Poll polls the first 20 values of your blocks.
- The wire addresses are already in the file, so there is no 0-based or 1-based conversion to do.
Once the values look right, export the tag list to Ignition, Kepware, Node-RED, Home Assistant or Voltrus SCADA.
